Abstract

A telecommunication device for the deaf (12, 14, 16, 20, 22, 24, 26, 28) operates under conventional Baudot communication protocol, but has enhanced features enabling it to handle interrupts either from a conventional or a similar TDD. The improved TDD is also capable of pseudo-duplex communication with a similar TDD in which each device transmits packets of characters alternatively to the other thus making it appear to the users that simultaneous transmission is occuring. The implementation of these features is done in such a way that the TDD is fully capable of communication with existing TDD devices and the device obeys normal rules and conventions for Baudot communication.
